In illustratingtheinvention hereinbeforeset forth, I have shown a band and balance wheel with connecting-rod and treadle suitable for operating sewing-machines. The angle at which the guideways are set allows the platform with a sewingmachine and its projecting band-wheel to pass in its descent without interfering with the foot-power mechanism. For other purposes, such as typewriters and others, where power from beneath is not required, the guideways may be set vertical instead of at an angle.

In lifting the hinged cover from position shown in Figs. 1 and 2 of the drawings the brace C (which is pivotally attached to its rear) is lifted until the cover passes a vertical line, when the brace begins to descend, traversing a slot or groove K in the rear, (more clearly shown in Fig. 3,) the cam-hook L engaging the said slot or opening in the strip J, and by this engagement and connection the platform is raised up with the machine into position.

The lifting of the movable cover from its extended position allows the platform with its machine to descend from the position formerly assumed below the top from View by its own gravity, except as its motion may be retarded by the strap H in a manneras follows: As the cover B and brace C are moved back to their position, as shown in Figs. 1 and 2, the cam-hook L, secured on the said brace C, is moved from engagement with the strap II, and the strip J thereon engages with the projection a,in order to support the movable table D in its lowered position and allow independent motion to the brace in traversing the extent of its run not required for moving the platform, as will be readily understood.

Having thus set forth my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. The combination, with a cabinet-case provided with a hinged cover, a movable platform, guideways by which said platform is 4 partially supported and guided, and a movable supporting-brace pivotally connected with said hinged cover, of apivoted wheel provided with strips connected thereto at one end, and at their opposite end connecting 5 with said movable platform and supportingbrace, respectively, substantially as and for the purpose set forth.

2. The combination, with a cabinet-case provided with a movable top, a vertically-ad- 5 justable platform, gnideways by which said platform is guided, and abrace or rod hinged to said movable top, of a pivoted wheel connected with said platform and said brace through the medium of strips, substantially 6 as set forth, and a pin or projection for engagement with one of said strips, substantially as described, and for the purpose set forth.

The combination, in a cabinet-case pro- 0 videdwithaverticalmovingplatform,ahinged cover, and a supporting-brace connected at one end with said covcrand at its opposite end provided with a cam-hook, of a pivoted wheel provided with straps attached at one end thereto, one of which connects with said platform and the other provided with an opening for connection with said can1hook, substantially as and for the purpose set forth.

4. The combination,in a cabinet-case of a 7g vertical movable platform and guideways for the same, a hinged cover, a brace connected at one end with said cover and provided with a cam-hook, a guideway for said brace, and a pivoted wheel provided with straps or hands con- 8 nected at one end thereto and at their opposite end connecting with said platform and brace or part thereof, respectively, in a manner substantially as and for the purpose set forth.
